如何使用JSTL从JSP页面获取值

Question

<%
    com.BeanPaket.kontrolBean kontrol = new kontrolBean();
    String epostavalue = kontrol.getEposta();
%>

<sql:query var="kutuphane" dataSource="${dataSource}">
    SELECT * FROM kutuphane.odunc_kitaplar WHERE eposta = ?

</sql:query>

如何在＆lt; %%＆gt;中输入我认可的值？标记到sql查询中以从数据库中获取列表？

Answer 1

试试这个：

<sql:query var="kutuphane" dataSource="${dataSource}">
SELECT * FROM kutuphane.odunc_kitaplar WHERE eposta = ?
   <sql:param value="${epostavalue}" />
</sql:query>
